Suspension Wear
Bushings, ball joints, and shocks don’t last forever. Signs of worn suspension components include:
- Clunking or Squeaking Noises: Often indicates worn bushings (control arm, sway bar) or ball joints.
- Bouncy Ride: Worn shocks or struts are no longer effectively dampening suspension movement.
- Uneven Tire Wear: Can be a symptom of worn suspension parts affecting alignment.
Fix: Inspect all rubber bushings for cracks or deterioration. Replace worn ball joints and tie rod ends. Upgrading to new shocks and springs can dramatically improve ride quality and handling. This is also a great opportunity for performance upgrades.
Engine Leaks and Gaskets
Older engines are prone to developing leaks as gaskets and seals age and harden.
- Valve Cover Gasket: Common source of oil leaks, usually visible on the top of the engine.
- Distributor O-ring: Another frequent oil leak point, often dripping down the back of the engine.
- Oil Pan Gasket: Look for leaks where the oil pan meets the engine block.
- Rear Main Seal: A more serious leak, often requiring transmission removal to replace.
Fix: Replacing gaskets like the valve cover or distributor O-ring is a straightforward DIY job. For more involved leaks, like the oil pan or rear main seal, it might be time to consider whether you’re comfortable tackling it yourself or if it’s best left to a professional mechanic.
Clutch and Transmission Concerns
Manual transmissions are robust, but the clutch is a wear item.
- Slipping Clutch: Engine RPMs increase, but the car doesn’t accelerate proportionally.
